The SIM card-based security identification scheme of Internet of Things device

Abstract

The identification information of the IoT device is an important content for the device configuration and management. In terms of identification carrier technology, compared to passive identification technologies such as barcodes and QR codes, security chips and modules as active identification carriers can actively initiate a connection to the platform side, without the need for identification reading and writing equipment to trigger, which is more automated and intelligent. However, the cost of the security chip is high, and the security level of the module is relatively low. Both of them need to be equipped with special software to realize the management ability of the identification. Neither of the two solutions can fully meet the needs of the IoT terminal. The IoT SIM card has the advantages of low cost, high universality, high security, two-way communication capabilities, etc., and can realize the function of active identification carrier. Therefore, this paper proposes a SIM card-based IoT identification management scheme. Through the management platform and the identification card application and other modules can manage the identification of IoT equipment, and at the same time, combined with the IoT security service system, the safety protection of identification is realized. This method is based on the BIP channel and does not require much management cost. It is a solution with high security, low cost and better convenience, and has a good application prospect in the field of equipment management.
